Problematic alcohol use, jealousy, and digital dating abuse: A dyadic analysis

Young adults engage in digital dating abuse (DDA), or threatening, monitoring, and controlling behavior towards a romantic partner through technology. Alcohol use and jealousy are well-established risk factors for in-person partner abuse but have not yet been investigated in couples in the context of DDA. Jealousy might be a relevant moderator in the digital context, potentially amplifying the negative associations between problematic alcohol use and DDA. Thus, we examine dyadic associations between young adults’ problematic alcohol use and DDA perpetration, with romantic jealousy as a moderator. Participants are young adult heterosexual couples ( N = 91 couples, M age = 21.03 years, 54.4% White, 19.2% Latino, 26.3% other). Results from actor-partner interdependence models suggest that men’s jealousy significantly moderates both the actor effect for men and the partner effect for women. In contrast, women’s jealousy significantly moderates the partner effects for both men and women. Men’s problematic alcohol use is a risk factor for their own DDA perpetration at high levels of jealousy and is a risk factor for their partner’s DDA perpetration across their own or their partner’s jealousy. Women’s problematic alcohol use is a risk factor for their partner’s DDA perpetration across levels of their jealousy. These findings underscore the importance of considering individual and relational factors in understanding DDA. The study highlights the need for dyadic interventions targeting problematic alcohol use and jealousy to prevent DDA. Future research should utilize longitudinal designs and diary studies to investigate in-the-moment processes and within-person variability.
